January 19, 1927, Serial No. 162,190, and in Canada November 9, 1926.

rlhe present invention relates to plows, and more particularly to those adapted for right and left hand plowing and has for its object to provide an improved plow of this type vwhich can be economically manufactured and operated and which is simple in construction and efficient in operation.

`Another object of the invention is to provide an improved plow having a plurality of plowing implements movable selectively to plowing position and arranged for movement to said position by the travel of the plow.

Another object is the provision in such a plow of elevating means for raising the plowing implements for movement selectively to plowing position, operated by. the travel of the plow while maintaining the plow supporting wheel or wheels in stable supporting contact with the ground and without disturbing the equilibrium of the apparatus.

Another object is to provide a two-way plow having plowing implements rotatable progressively in the same direction by contact of the implements with the ground to bring them successively to plowing position, together with means operated also by the travel of the plow, as for example, by the rotation of the supporting wheel or Wheels, for elevating the implements for such movements while maintaining the weight ,o-f the apparatus on its supporting wheel or wheels in stable equilibrium. More specifically stated, it is an object of the invention to provide such an apparatus in which such elevation of the implements and the adjustment of the same to plowing position may be rapidly accomplished and secured with a minimum of effort by merely releasing such parts for operation by the normal travel of the plow in the work.

A further object is to provide an apparatus of .the character described provided with means operated, for example, by the movement of the implements to plowing position, for correcting the inclination of the right and left hand implements respectively to compensate fo'r the depression of one of the wheels in a furrow.

A further object is to4 provide such an apparatus capable of operation rapidly, in short space, with a minimum of attention on the part of the operator so that the latter may devote his attentionV primarily to the operation of the tractor, particularly on uneven ground or a hillside. v

To these and yother ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, thenovel features being pointed out in thev claims at the `end of the speciication. I i

The present application is a continuation in part of an application filed-by me for improvements in plows, June 10, 1925, and bearing Serial Number 36,090.

The invention embodies an improved right and left hand plow which may be horse drawn or pulled by a tractor as desired, and which comprises supporting wheel means such as the pair of wheels l0 and 10a carrying a main frame including the angularly constructed axle members 1l and 12 connected in any suitable manner, but preferably by the transverse bar 13 forming in the present instance a part of the axle. The main frame further includes the side bars 14 and 15 which are connected with the axle members preferably through the medium of the transverse bar 13. The side bars are bent to form transverse portions which have forwardly extending spaced extensions 16 and 17 between which is pivoted at 18 a draw bar 19. The draw bar is preferably provided at its rear end with a notched or toothed segment 2O and is held in diiferentpositions of adjustment by a latch bolt 21 reciprocally mounted in a bracket 22 and held in locking position by a spring 23l disposed upon the bolt between the head`24 thereof and the bracket 22 as shown in Figure 3. The outer end of the draw bar which is provided with a suitable clevis 25 of any desired construction may be raised or lowered to suit different operating conditions or in accordance with the depth at which the plows are operated. The draw bar is preferably reinforced or braced in front of the frame extensions 16 and 17 by a pair of relatively short bars 26, the front ends of which are rigidly secured to the draw bar and the rear ends connected with the pivot bolt 18 thereof as shown in Figure 3. The frame members 14 and 15 and the draw bar 19 are together braced by a pair of convergently arranged bars 27 having their front ends connected preferably with the draw bar pivot bolt 18 and their rear ends connected with the frame members in any desired manner.

The two sets of plows indicated generally at 28 and 29, are provided with short beams or standards 30 and 31 respectively, having their inner ends bent and suitably secured to a rigid frame construction adapted to swing about a transverse axis afforded preferably by the axle or pivot bar 13, said frame preferably comprising the angular shaped bars 32 and 33 which are connected in any suitable manner and through which the pivot bar 13 is extended, said frame being held against lateral movement by suitable collars 34 rigidly secured on the pivot bar as shown in Figure 3. The frame members 14 and 15 have their rear ends pivoted upon the bar 13 and are held against lateral movement thereon preferably by suitable collars or brackets 35 which are also shown in Figure 3. rlhe pivoted frame construction embodying the bars 32 and 3 3 while suitable for the purpose provided, may be modified or changed as desired. The frame is provided in front of the main plowing implements with the usual colters 36 for breaking or turning the sod in advance of 'the mold boards, the same being connected with the frame nby suitable standards 37 as shown in Figures 1 and E?, The frame members and 33 are p; ith exteni l portions 33 and jf for e' another and while the plow is advancing, whereby the continued turning of the frame is effected from the plowing position shown in Figure 2 to a position such as shown in Figure l, the frame having been preferably raised and released for turning by means which will be hereinafter described.

The bar 32 of the plow carrying frame is provided at its upper side with a removable portion 32a and the opposite bar 33 is provided at its lower side with a removable portion 33a. These portions serve to increase the depth of the bars at the bearing points of the axle 13.to provide sufficient material to permit one of the bearings for the axle to be offset upwardly and the other downwardly so -that the frame will remain substantially horizontal while the axle is inclined alternately in opposite directions to the horizontal, which is desirable since one of the wheels of the plow operates within while the other travels without the furrow. By thus offsetting the bearings for au axle, or drilling the holes for the shaft 13 at the proper inclination to take care of the difference in the operating positions of the wheels, the plow-carrying frame, in either position to which it is swung will remain substantially horizontal. This serves to maintain the plows on an even keel regardless of the fact that one wheel operates within the furrow, the bottom of which is indicated by the dotted line 34a in Figure 1.

Such construction provides a compensating means operated by the rotation of the plow carrying frame for correcting the inclination of the implements in plowing position with either of the wheels in a furrow, but, of course, other and lequivalent means will suggest themselves to those skilled in the art for accomplishing the same result.

The portions 32a and 33a of the frames, though shown as being removably connected with the bars by the screw bolts 35a may be formed integral with said bars if desired. By making said members removable the frame may be more conveniently applied to the shaft 13.

lt will be understood that a certain amount of the dirt thrown over. by the mold-board of the plow will fall back into the furrow and y partially fill the same, particularly when plowing in relatively soft ground. The wheel operating in the furrow may therefore, not travel upon the extreme bottom of the furrow, but upon a certain portion of the dirt which falls intothe same, the wheel 10a be ing indicated in such a position in Figure 1.

The revoluble frame is normally held du ing' operation of the plow in th posi" i shown in e 1 by the locliin shown in llie'i s 6 and 7. '""Vs v ly compr a yoke s :posed betwe a pair of t h aped tween the frame extensions 16 and 17 by a bolt 42.

The revoluble frame is prevented from swinging upwardly by a latch member 43 pivoted at 44 between the bracket members 41 and is held in latching position as shown in Figure 6 by a spring 45 on a rod 46, the rear end of which is pivotally connected with the latch at 47 while its front end is slidably supported by a bracket 48 which is clamped upon the frame extensions 16 and 17 by a bolt 49 which is also adapted to secure the bracket 22 and an additional bracket .50 provided for a purpose which will hereinafter appear. The spring is adapted to urge the latch 43 to the position shown i vFigure 6, the'latch being automatically displaced by the ends 38 and 39 ofthe frame when moved downwardly into engagement therewith but being automatically returned bythe spring 45 when said ends reach their lowest position in the yoke 40. Release of the frame for a rotating movement is effected by moving the yoke 40 to the dotted line position shown in Figure 6, which is accomplished through the medium of a crank arm 51 connected with the yoke 40 and actuated by a rod 52 slidably disposed in the bracket and being automatically returned by a spring 53 when released. The rod 52 is provi-ded with a head or clevis 54 to which is pivotally secured a forwardly extending connection 55 having pivotal engagement with an arm 56 of an operating lever 57 which is pivoted at 58 to one of the brace members 26 as shown in Figures 1 and 3. The lever 5 7 may beconveniently moved to .release position from the drivers seat on the tractor, not

' shown, either by hand or foot as desired, its' length and inclination being regulated to suit the particular type of tractor used.

The mechanism for regulating the depth at which the plows are adapted to operate and for raising the frame upon which the plows are-mounted include cooperating parts I for effecting both movements as will hereinafter appear. f

The raising of the main frame at the end of each furrow to a position at which t-he plow carrying frame can be readily swung upon its transverseaxis or about the shaft 13 is effected by means of a suitable clutch such as that illustrated in Figures 4and 5, these views showing the clutch respectively in normal release and coupled positions. Upon "advancement of the Wheels with the clutch in coupled position the mainframe including the shaft or pivot bar 13 willbe elevated as indicated in Figure 2, by means'of this clutch mechanism.

rlhe clutch is preferably shown applied to one wheel only but may be applied to both if desired. It embodies a drum 59 rigidly connected with the w'heel 10a and normally rotating within the arcuate portions 60 of a casing 61 having a sleeve 62 journalled on oted at 66 to an upstanding support 67, preferably comprising an inverted U-shaped frame member, the lower ends of which are suitably connected with the forwardly extending frame member 15 as shown in Figure 4. The forward leg of the U-shaped frame member is provided with a series of notches 68 adapted to receive a pawl 69 on a stem 7 0 slidably mounted in a lug 7101i the lever 65,

CLI

the stem carrying a spring 72 for nnoving the pawl to locking position when released. An operating-rod 73 for releasing the pawl 69 is connected at its inner .end with the stem and at its outer end with a hand grip lever 74 of any preferred type.

The casing 61 is coupled with the drum 59 when desiredl by a lever 75 having a roller. 76 adapted to take into notches` 77 of the drum as shown in Figure 5. The lever 75 is pivoted to the casing at 78 and is provided with an operating extension 79 similar to an extension 80 on a control lever 81 which is pivoted to said casing at 82 and operatively connected with the lever 75 by a link 83. A spring 84 is adapted to move the lever 75 to a clutching position as shown in Figure 5 when the lever arm 8O is disengaged from a control lever 85 pivoted at 86 to an arm 87 rigid on the shaft 13 and paralleling the angular extension of the axle 12 which is also rigidly connected with the shaft 13. The control lever 85-is held in the locking position shown` y in Figure 4 by aspring. 88 and carries at its lower end a roller 89 for normally engaging either of the lever arms 79 and 80, whereby to render the clutch inoperative. In the normal position of the lever' 85 the roller 89 is disposed within one of the notches 90 formed by the relatively longand short lugs 91 and 92 respectively which are projected from the casing 60 as shown in Figure 5. The control lever. 85 is adapted to be moved to release position by a cable 'ori other suitable connec- Vtionw93 extended forwardly to apoint within convenient reach of the driver. Upon release of the control lever from the position shown in Figure 1 the spring 84 will move lever'81, link 83 and lever 75 to position the L roller 76` in one of the notches 77 of the drum 59, whereby to couple the wheel 10a/with the casing 60, so as to rotate the latter, thus mov- A into one of the notches 90 and engage one or the other of the lever arms 7 9 and 80 to disconnect the clutch as shown in Figure 4.

' To lower the plows, the lever 85 must be again released, this time from the position shown in Figure 2 whereby the clutch will again be rendered effective to rotate the casing 6l aud arm (i3 from the position shown in Figure 2 back to that shown in Figure l, the link G4 during such movement serving to pull the main frame down and permitting the plows to enter the ground ready for plowing the next succeeding furrow.

The depth at which the plows are operated can easily be regulated by raising or lowering the. lever as desired.

The lever 85 and arm 87 when in normal clutch releasing position as shown in Figures l and 4 form means for bracing and supporting the main frame in cooperation with the arm G3, link 64 and U-shaped frame member 67.

In operation, as indicated by the above description of the construction, as the plow reaches the end of a furrow, lever 85 may be pulled forwardly, as by means of thecord 98, to couple the elevating means to the wheel, with the result that the plow frame is raised by the rotation of the wheel, or in other words, by the travel of the plow or the power by which it is drawn, and the plowing implements lifted until they contact lightly with or substantially clear the ground in which position they are locied by the operation of the elevating mechauisn'i. Lever 57 is operated, preferably, though not necessarily at the same time that' the elevating mechanism is released as above described, to release the rotary plow frame so that the engagement of the implement and frame portions with the `round immediately starts rotation of the frame on which the implements are carried, on its axis, or in the present instance on the crank axle 13. It will be noted that the points' and heels of the implements and the ends of the landsides and the ends 38 and 39 of the rotary plow frame, together with the colters, provide a plurality of contacts with the ground by means of which the rotary plow frame is rotated as if a wheel rolling on the ground to positively and continuously rotate it from one position of adjustment to another, or in other words, until the frame has been turned through an angle of 1800 to bring the other plow or plows down into plowing position in which position they are secured by the locking engagement of one of the frame ends 88 or 39 with the device described for that purpose.

The sin'iultaneous release of the elevating mechanism and the rotary plow frame serves to raise the latter with suiticient rapidity so that the implements and their frame rotate in light contact with the ground, to avoid the lifting of the plow supporti-ng wheels from the ground and such simultaneous release and operation of these mechanisms contributes to the rapidity and ease of operation of the plow at the end of the furrow to change from a right hand to a left hand plowing implement or vice versa for reverse movement back across the field in the opposite direction. It will be noted as one of the important advantages of the invention that the mechanism for elevating the implements for reversal is interposed and operates between the supporting wheel means and the implements so as to raise the implements and the frame by which they are carried by downward pressure on the wheel means-as a support, so that the weight of the parts is maintained on the wheels without disturbing their contact with the ground. By this arrangement, therefore, the implements and their supporting frame means are positively raised relative to the wheels so that the implements are raised and secured in elevated position in a positive and reliable manner. The apparatus thus operates without disturbing the equilibrium of the apparatus as a whole which is particularly advantageous on uneven hillside.

These plow raising and adjusting movements are readily accomplished during the normal turning of the plow at the end of,

the. furrow. When a plow or tractor is employed it may even be left continuously in high speed as such movements are accomplished during the turning of the plow and when the plow has been turned to commence the neXt furrow, the eleva-ting mechanism is again tripped to positively lower the implements and their supporting frame means and drive the implements into the ground for plowing in the opposite direction. As applied to a two-way plow the rotation of the frame for substituting a plowing implement of different hand, serves to adjust the inclination of the plowing implement to compellsate for the depression of one of the wheels in a furrow. But of course the invention may also be employed with other than right and left hand implements, as for example, for substituting one kind of implement for another for plowing in the same direction.

The operation of the plow is thus rapidly accomplished by the operator either from a position on the plow frame, for example, or on the tractor, Vand by the force by which the plpw is drawn, without requiring any attention or exertion on the part of the operator to move the relatively heavy machine parts other than the slight and momentary effort of tripping the elevating and rotary plow supporting parts as described, which automatically complete their cycles of operation and reiock themselves in position.

The construction employed i* exceedin simple and compact. The frames are 'i erably, but not necessarily pivoted fureci. i;

4Such construction makes possible likewise a minimum of size, the length, for example, be.- ing exceedin ly short, particularly for a gang plow, and a apted for operation by'a small tractor. The above and other'advantageous.

features of construction and operation provide a plow which practically eliminates dead urrows, back furrows and idle driving at the furrow ends, and one which is rapid and easy to operatehnot only on level ground, but also Y, on uneven'grund and in hillside plowing.

While l have illustrated and described one embodiment of my invention, it will be understood that different modifications of the construction shown may be readily made withoutdeparting from the principles of the invention aswmbodiedv in the claims.
